PROCESS OF MAKING SOFT TRANSPARENT SODIUM OIL-SOAPS.

No Drawing.

To all whom it may concern Be it known that I, JAMEs W. RYDER, a citizen 'of the United States of America,

and a resident of New York, county and ess which is carried out without the aid of any potash employed in making soft transparent oil soaps- The present scarcity and exorbitant price of potash render its use prohibitive in the art of producing soft oil soaps. The novel process forming the sub ject matter of this invention thus dispenses with the use of potash altogether and soft,

transparent oil soap is produced by means of caustic soda, especially caustic soda lye. Thishas primarily been attained by preparing the oil before safplonification so as to render it easily saponi able. In order to prepare the oil, it is simply heated to a certain temperature and alcohol admixed therewith. The alcohol modifies the oil and renders it susceptible for the action of the c'aus-, tic soda lye which then is added to the prepared mixture of oil and alcohol.

Various kinds of oil may be used in accordance with the present process, for instance linseed oil, corn oil, cotton seed Oil, olive oil, soy bean oil, cocoanut oil, deodor- Of the various kinds of alcohol that may be employed, I prefer to use the denatured alcohol on account of its reasonable price and its efficiency because it is ethy'lic alcohol which is known to'be chem ically very active. I

In carrying the present invention into efiect, I substantially proceed as follows: A

vegetable oil, for instance linseed oil is heat-' ed to a temperature of from 100-110 F. At this temperature the alcohol (preferably denatured alcohol is incorporate with the Specification of Letters Patent.

oil. The mixture is well agitated until a uniform mass has been obtained.- Now caustic soda lye is added having a temperature of from 90 -F. and the mixture well agitated. After the action of the lye on the mixture of oil and alcohol is complete some Water 1s added at ordinary temperature. The entire mixture is now boiled until a complete combination has been effected and soft transparent soap of proper consistency is obtained; During the boiling of the mass the alcohol evaporates and is not found in the finished product. has performed its useful functions during the process of manufacture by first modifymg the Oil at a certain temperature so that the oil is more susceptible for the action of the alkali, and second the alcohol effects that a, transparent soap is directly produced during the process of manufacture.

The proportions in which the various components may be employed vary within reasonable limits particularly on account of the various kinds of oil that may be used. One formula giving good results with most of the. vegetable oils is as follows: About 100 pounds of vegetable oil are heated to a temperature of from 100-110 F., then 3 .pounds of denatured alcohol are incorporated and about one half. theweight of the 011 of caustic soda lye of 36 B. is admixed having a temperature of from 6090 F. For certain oils the caustic soda lye may be of a different strength but of proportionate quantity, less of the strong and more rof the weak lye may be required. To the mass so far described 30-60 per cent. of water are added at ordinary temperature and the entire mixture is then boiled until transparent soap of the desired consistency has been obtained which is indicated by the usual tests-.lffgQiThe consistency of the resulting soap varies according to the length of time during which the boiling of the mass is continue as required for specific uses. ished soap is allowed to cool.

I claim as my invention:

1. The dprocess of roducing soft, transparent so ium soaps rom vegetable oils directly during manufacture consisting in preparing the oil by admixing a few per cent. of denatured alcohol therewith, saponifying the mixture of oil and alcohol by caustic soda lye, adding water up to about one half Now the fin- However, the alcohol Various grades may be made of the quantity of the mixture, and boiling the resulting mass until perfectly saponified, transparent soft soa is obtained. Y

2. The process producing soft, transparent sodium soaps from vegetable oils directly during manufacture consisting in sapomfying the oil by caustic soda lve, adding Water up to about one half I quantity of the mixture, and boiling the resulting mass until perfectly saponified, transparent soft soap is obtained.

3. The process of roducing soft, transparent sodium soaps rom vegetable oils directly during manufacture consisting in preparing the oil by heating it to about 100- 110 F. and then incorporating a few per cent. ofalcohol: therewith, saponifying the mixture by caustic soda lye, adding water a y p 1,212,818

pounds of vegetable oil to a temperature of from 100-110 F., incorporating with the heated oil about 3 pounds of denatured alcohol, admixing then about 50 pounds of caustic soda lye of 36 B. having a temperature of from 6090 F., adding about -60 per cent. of water, and boiling the resulting mass until transparent) soap of the desired consistency is obtained.

5. The process of roducing soft, transparent sodium soaps from vegetable oils directly during manufacture consistingfin preparing the oil at atemperature of 100110 F. by admixing therewith a few per cent. of alcohol, saponifying the mixture by caustic soda lye having a temperature of from 60 to 90 F., adding water up to about one half of the quantity of the mass, and boiling the resulting mass until perfectly saponified, transparent soft soap is obtained.
